When a project has a particularly long timescale it is essential to rethink the HVAC strategy. District energy schemes, for example, are typically rolled-out gradually, linking additional buildings to the network over an extended period (years rather than months.
These types of project can encounter a number of problems as activities on site expand. Plans change over time and it can be impossible to anticipate exact requirements so far ahead of project completion. From a technical viewpoint, there is an enormous difference between the part load condition for phase one and the full load condition at full build out of a major project. This presents a significant challenge for HVAC designers, as they need to create heating/cooling schemes that are reliable and energy-efficient over an extremely broad range of operational conditions.
